TUBING COMPANY,

GRAIN REDUCTION AND SPECIFICATION forming part of Letters Patent No.297,761, dated April 29, 1884.

Application `filed May 3i .To all whom it may concern:

Be it known that l, JOHN M. Casa, a citizen of the United States,residing at Columbus, in the county of Franklin and Statelof Ohio, haveinvented certain new and useful Improvements in Grain Reduction andSeparating Machines, of which the following is a specification. e

This invention relates to an improved machine for splitting wheat andseparating'1 `the germ and impure matter which may be confined withinthe crease of the wheat.

It consists of'a machine comprising devices for splitting the grain, anda compound reel constructed in such a manner that three separations maybe made, the broken wheat passing off by one spout, the germ which hasbeen removed from the grain by another spout, and the iiour or seamimpurities which, may have been liberated by another spout. `The reelemployed for this purpose is double, being formed with an innerwire-cloth screen and a finer cracking devices are both mounted in thesame frame and driven by the same connections.

In this invention I use a wheat-reduction machine for which I havealready obtained Letters Patent, or any other form ofwheat-reduction-machine may be employed; but I prefer this machine onaccount of its simplicity and effectiveness in operation.

In the accompanying drawings, Figure 1 is a front view of the apparatus.Fig. 2 is a vertical longitudinal section, showing the breaking andseparating mechanism more fully.

The breaking-machine here represented consists of a toothed roller, 1,and a concave, 2, supported on the fulcrum 3 and adjusted by means ofscrews 4,an'd carrying a toothed faceplate, 5, which, by means of thescrews 4, is set at any required distance from the breaking-roller 1.This breaking mechanism Works in a casing, 6, surmounted by a hopper, 7,in which are an adjustable feed-board, S, and a corrugated roller, 9, toregulate the feed. By this apparatus the wheat is split longitudinallyin halves.- In this breaking operation the germ at the end of the Wheatbecomes liberated, and also any impure matter which may PATENT OFFICE.

ken wheat and liberated product pass through the spout 10 to the doublereel below. The inside reel, 1l, is made with wire-cloth, of meshsufficiently coarse and open to permit all the germ, or middlings thatmay have been made in the breaking operation to drop through the mesh esof the wire-cloth. This product, dropping through the central or innerreel, falls upon a silk bolting-oloth upon the outer reel, 12, which isof greatly-reduced mesh, being in practice ordinarily about No. 12boitiug-cloth.

" This silk cloth retains the germ and middlings,

the dust from which falls down into the boX or trough 13, and isconducted off by the conveyer 14 and spout 15. oft' through the spout15, is very impure, and is ordinarily used for feed. The productpassingover the tail of the reel 11 at 16 consists of half-grains'ofwheat. This may be sent to the machines for additional reductions, or itmay be sent to the ordinary millstone for grinding into flour. The germand m'iddlings product, passing through the screen 11 and out throughthe openings 17 in the screen 12, drops down into the hopper or spout18, and is conducted off and ordinarily sent to smooth rolls for thepurpose of crushing or for further treatment.

In this invention I accomplish the removal of the germ product and theimpure material which becomes embedded within the crease of thewheat-berry in one common machine.

I am aware that bolts have been made with cloth pla-ced within clothor'a double reel; but my invention combines in one common frame areduction-machine and a bolting apparatus, whereby the wheat is brokenand three complete scparations of the material are made.

This product, taken reel isnecessarily of silk cloth sufficiently fine.

to separate the dust and fine impurities from the middlings and germ.'

The rotation of the double reel may bel effected by any suitablemechanism-as, for eX- ample, a belt, 19, driven by a pulley on the shaftof the roll l, and running a pulley, 20, connected by bevel-pinions 21with the reelshaft 22.

The reels may, if preferred, be driven inde- IOO (No Modell.)
